l BoLTING-UP DEVICE.

Application led September 9, 1919.

and useful mprovements in Bolting-Upl Devices, of which the following is a speciiication.

This invention relates to means for drawing together or bolting up metal plates in structural iron and steel work, such as the metal lplates of iron ship hulls and the like; and it consists in a novel means for quickly and temporarily bolting up such plates preparatory to uniting them by rivets or welding them.

The metal plates used in making hulls of vessels ordinarily do not lit exactly and to enable the plates t'p be properly united it is essential that their. overlapped edges should be brought tightly together before the rivets are applied. It has 'been customary to tem porarily bolt these plates together by insert-` ing ordinary bolts through some of the registering rivet holes and then applying nuts to the bolts in the usual manner. Such op` eration is tedious and time consuming and requires many turns of the nuts on the bolts to bind `the plates tightly together.

The object of my invention isto enable the securing bolts to be very quickly applied and tightened; and as readily released. For this purpose I employ novel bolting up 'devices hereinafter fully described, each comprising in brief, a bolt transixing the plates; two opposite wedges slotted for the passage of the bolt andadapted to be inserted between the plates and the nut on the bolt; and novel means for quickly and easily forcing the wedges together so asl to cause the bolt to forcibly bind the plates together, as the wedges bind between the outermost plate and the nut on the bolt. I also provide novel means whereby the wedges when tightened can be temporarily locked together to prevent them loosening up under the jarring of the riveting machines.

I will explain the invention with reference to the accompanying drawings to enable others skilled in the art to readily adopt and use the invention and then summarize in the claims appended hereto the essen-l tials of the invention and novel features` of constructions and combinations of parts for which protection is desired.

In said drawings: Figure 1 is a top` plan view of the at present preferred form of bolting up devices with the parts readyto tighten the bolt.

Fig. 2 is a vertical longitudinal section on the line 2-2 of Fig. 1.

Fig. 3 is a similar section showing the parts ready to tighten the wedges.

Fig. 4 is a transverse section on line 4-4, Fig. 1.

Fig. 5 is a detail view showing the slotted bolt head washer.

Fig. 6 is a side elevation ofa frame` member.

In the drawings .P and P represent portions of two metal plates, such as are used in the hull of an iron vessel, or other structural iron work, which are to be riveted or welded together; and which are usually perforated on their overlapping edges for the large enough at one end to be readily'slipped over the end of the bolt 1 and a contracted portion adapted to engage with the slots 1a in the end of the bolt (see Fig. 5), and when so engaged the washer plate forms a detachable head for the bolt.

In applying such a bolt to the plates P, I), it is not necessary to remove the nut 1b from the threaded portion of the bolt; whereas if a headed bolt is used, it would be necessary to entirely remove the nut from the bolt and insert the bolt through the plates; Whereas the slotted vwasher-plate 2 can be readily detached from the bolt and the latter slipped through the plates, and the washer-plate reattached thereto without having to remove the nut from the bolt.

Interposed between the nut 1b and outermost plate P is a pair of opposed wedges 3, each provided with a longitudinal slot.3n to accommodate the stem of the bolt` and each may have its larger end concaved as shown at 3b. These wedges are adapted to ride one upon the other and by properly relatively moving them the wedges 3 will be tightly bound between the nut lb andthe outermost plate: and exert forcible longitudinal tension upon the bolt and the plates bebound tightly together between the nut 1b and the headof the bolt or washer-plate 2, as shown in Figs. 2 and 3.

When the plates are thus securely clamped the wedges 3 may be secured in position, if desired by suitable means. I preferably employ a thin metal locking strip 4, inserted between the wedges, and slotted for the passage of the bolt, and when the wedges are caused tofforcibly bind the bolt and plates together the ends of the locking strip ,4 are bent over the outer ends ofthe wedges 3, as shown in dotted line in Fig. 2, and effectively prevent the Wedges jarring loose durin the riveting ofthe plates. l

n order to quickly and forcibly apply the bolting up device I provide means for forcibly telescoping the wedges together. The

preferred means for this purpose comprises a metal frame havin Y parallel side members 5 spaced apart su ciently to allow the wedges 3 to enter between them; and united at one end by a transverse end member 5,

-which is adapted to engav'e the lconcaved end of one of the wedges. onnected with the other end of the clamping frame or members 5, opposite the end member 5f, is an actuating member which, as shown in Flgs. 1-4, has a head portion 6, adapted to engage with the concaved end of the adjacent wedge 3, and a short handle portion 6a by which the'head can be rocked. lThe actuating member can be adjusted as indicated in dotted lines in Figs. 2 and 3, to engage the outer end of the adjacent wedge 3, and then by turning the handle in the direction indicated by the dotted arrow the end of the head 6 engages one wedge 3, while the member 5 of the frame engages the end of the opposite wedge and both wedges can be simultaneously moved `in opposite directions by the proper turning of the said actuating membermand the wedges cause the bolt to tightly bind the plates together as indicated in Figs. 2 and 3.

The actuating member ispreferably pivoted between the side members 5 of the frame by means of a pin 6b having bearings in openings or slots in the side members 5'. To enable an eXtra amount of slack between the nut and plates to be readily taken up,

lapped perforated' portions of the plates v are brought into juxtaposition; then a b'olt 1 is slipped through registering holes in the plates. In the construction shown in F 1g.v 1, the nut 1b is left on the bolt4 and the Wedges and plates are strung on the bolt before its slotted end is inserted through the holes in the plates; and after the bolt is inserted the `washer-plate is engaged with the slots in the bolt end, thus loosely tying the plates together. When a headed bolt is used the nut l must first bel removed therefrom and after its threaded end is passed through registering holes in the plates the 'wedges are slipped onto the-bolt,

and the nut screwed on the bolt exterior to the wedges. In either case after the bolt and wedges are temporarily engaged with the plates as described, the frame 5 is placed around the bolt and wedges; then the wedges are forcibly moved by manipulating the actuating member so as to force the wedges together and cause them to forcibly bind between the nut and the outermost plate; thereby binding the two plates tightly together; then the frame can -be removed; and if desired the metal retainer strip 4 (previously placed between the wedges) can have its ends turned over the ends of the wedges to lock them in place; or wedges may be roughened to insure suficient friction therebetween to prevent them being disengaged or loosened by -jarring.

The novel bolting up devices are convenient for use by bolters, reamers, and riveters, and renders it easy to bolt up the plates, and also to knock down, after the plates are riveted together. These bolting up devices are adapted to be used in ship construction; on bridge work, and on other construction work where bolting up is done and will save much time and labor.

These bolting up devices do not require skilled operators, are simple in construction and operation, and will effectively perform the work.
